Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B is a genuine double-acting profile-type cylinder with a Ø100mm bore, 350mm stroke and a built-in 4M310-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B
The SAUF100X350S-08B is a double-acting profile cylinder with a built-in AirTAC 4M310-08 5/2 solenoid valve on the cap. One DC24V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel makes it shorter than an ISO 15552 cylinder of the same bore. The 1/2 inch cylinder port and M20x1.5 rod thread handle heavy loads.
Size force strictly within the 0.15-0.8 MPa valve window, even though the cylinder body rates to 1.0 MPa. At 0.5 MPa it pushes 3927 N and pulls 3681 N. The safe working load is roughly 2356 N, allowing a vertical lift of about 200 kg with a 2:1 margin. The valve flows 25 mm2 (Cv 1.4) at up to 4 cycles per second. This -S model includes a piston magnet for CMSG/DMSG/EMSG switches.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B Is Used
Heavy Press Stand
Decentralized pressing station where the integrated 4M310 valve provides immediate high-force actuation without routing long tubing back to a central manifold.
Pallet Lift Gate
Independent vertical lifting gate using the piston magnet for position feedback, saving manifold space while delivering 3927 N push force at 0.5 MPa.
Bulk Divert Arm
Single-signal diverter on a packaging line where the built-in valve handles 4 cycles per second, eliminating the need for a separate remote valve island.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B the Right Choice?
Compare neighbours: the 80 mm bore pushes 2513 N at 0.5 MPa, while this 100 mm bore pushes 3927 N. Verify your coil is DC24V with terminal entry. The rod retracts when energised; reposition the valve to extend on signal. The assembled unit operates at 0.15-0.8 MPa, never quote the 1.0 MPa body rating for the assembled SAUF. The valve routes air and is not a lock; add an external rod lock or pilot-operated check valve to hold a load. For the 350 mm stroke, use external guides to prevent rod bending and side-load wear.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF100X350S-08B FAQ
It pushes 3927 N and pulls 3681 N at 0.5 MPa, reaching 6282 N at 0.8 MPa. The built-in valve is a 4M310-08 (1/4 inch port, Cv 1.4) running on DC24V. The cylinder body rates to 1.0 MPa, but you must size force within the 0.15-0.8 MPa valve operating window.
By default the rod retracts when the coil is energised. You can reconfigure it to extend-when-energised simply by repositioning the valve. Because the valve only routes air, it is not a load lock; add an external rod lock or pilot-operated check valve if you need to hold a load.
